Casing configuration for revolver cartridge loader

ABSTRACT

A casing configuration for revolver cartridge loader embodying a rotating shaft member; a packing member; a casing, an outer circumferential surface of which is configured with a plurality of successional arc-shaped grooves, and a shaft hole is defined central of the casing, moreover, a plurality of cartridge bores are equicicumferentially configured around the shaft hole. Configured side of the shaft hole is a locating hole, which provides for a spring and a ball bearing to be disposed thereinto, and two locating holes, which provide for two inserting pins to respectively penetrate thereinto and fix position. The shaft member is movably disposed within the shaft hole. The successional arc-shaped grooves thus allow for quickly grasping onto with fingers, thereby enabling rapid and convenient loading of cartridges into a cylinder of a revolver.

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to an improved casing configuration forrevolver cartridge loader, and more particularly to the casing thatadvantages fingers of a user to grasp hold and thereby have contactcontrol of the casing, which thus benefits the user to rapidlyaccomplish task of loading cartridges.

(b) Description of the Prior Art

Regarding conventional art of a loader for a revolver, U.S. Pat. No.6,308,451 B1, U.S. Pat. No. 5,842,299, U.S. Pat. No. 4,313,275 and U.S.Pat. No. 4,202,124 all disclose loaders for use in revolvers. However,casings utilized for loading cartridges in such conventional art are ofa cylindrical configuration, and are adopted with a smoothcircumferential surface, and thus difficult for a user wanting to usetheir fingers to grasp hold of the loader in a dark environment,particularly in an emergency when the fingers will probably shake fromnervousness. In addition, should the fingers be stained with grease, thefingers will easily slip away from grasping hold of the cylindricalcasing. Furthermore, the hand holding the loader already loaded withcartridges easily misaligns the loader with a cylinder of the revolver,and is thus difficult to quickly load the cartridges into the cylinder.Hence, research task of the present invention is in providing the casingthat allows the cartridge loader to be conveniently grasped hold of andwhich thereby facilitates contact control by the user.

SUMMARY OF THE INVENTION

Accordingly, a primary objective of the present invention is to providea casing configuration for revolver cartridge loader that allows fingersto manipulate and expedite effective grasping of a loader, and therebyallow achieving rapid loading of cartridges into the loader and quickalignment of the loader with a cylinder of a revolver, which thuseffectuates rapid release of the cartridges into the cylinder.

Referring to FIGS. 1, 2, 3, 4, 5 and 8, which show a casingconfiguration for revolver cartridge loader of the present inventioncomprising:

A rotating shaft member 10, front of which forms a shaft member 12, anda pin 121 is inserted into a front end thereof. A pointed gear member 14is configured on a rear side of the shaft member 12 and formed integraltherewith, and which is provided with a plurality of pointedprotuberants 141. A small circular collar 15 of smaller externaldiameter is configured on a rear side of the pointed gear member 14 andformed integral therewith. A large circular collar 16 of larger externaldiameter is configured on an outer side of the small circular collar 15.A circular ring 18, which provides for fingers to rotate, is formed on arear side of the large circular collar 16, and a coarse surface 181 isconfigured on a surface of the circular ring 18.

A packing member 20, a center of which is provided with a circularlinking hole 22, movably rotates atop a circumferential surface of thesmall circular collar 15. Moreover, a plurality of protuberants 24 areformed on an outer periphery of the packing member 20.

A casing 30, an outer circumferential surface of which is configuredwith a plurality of successional arc-shaped grooves 32. A shaft hole 34is defined central of the casing 30, and a plurality of cartridge bores36 that penetrate through the casing 30 are equicicumferentiallyconfigured around a center line of the shaft hole 34. A locating hole 37and two locating holes 39 are configured side of the shaft hole 34,wherein the locating hole 37 provides for a spring 33 and a ball bearing35 to be disposed thereinto, and the two locating holes 39 provide fortwo inserting pins 38 and 38′ to respectively penetrate thereinto, andhave fixing position functionality.

The shaft member 12 is movably disposed within the shaft hole 34, andthe pin 121 rotatably displaces left and right amid spacing between thetwo inserting pins 38 and 38′.

Accordingly, fingers 50 can quickly grasp hold onto the successionalarc-shaped grooves 32, which thereby enables rapid and convenientloading of cartridges 60 into a cylinder 70 (see FIG. 9).

The arc-shaped grooves 32 are six in number, and are respectivelyconfigured so as to be equidistributed on the surface of the casing 30,which thereby facilitate grasping hold with the fingers 50.

Referring to FIG. 1, six notches 26 are configured so as to beequidistributed on an outer periphery of the packing member 20, andwhich thereby form the six protuberants 24, and distance between theadjacent protuberants 24 are such to be equal. Each of the protuberants24 extend interior of the respective cartridge bores 36, and flanges 241on two sides of each of the protuberants 24 can come in contact with aninner wall surface 361 of the respective cartridge bores 36 (see FIG.4).

Referring to FIG. 5, the pin 121 exerts pressure on the ball bearing 35while displacing between the two inserting pins 38 and 38′, which thusactuates up and down flexible translatory movement of the ball bearing35 within the locating hole 37.

Referring to FIG. 1, wherein the cartridge bores 36 of the casing 30 aresix in number, and are configured so as to be equiidistributed in thecasing 30.

To enable a further understanding of the said objectives and thetechnological methods of the invention herein, the brief description ofthe drawings below is followed by the detailed description of thepreferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 3, 6 and 7, which show a plurality of cartridges 60respectively disposed in cartridge bores 36, at which time pointedprotuberants 141 are respectively positioned between adjacent cartridgebores 36. A pin 121 is located between a ball bearing 35 and aninserting pin 38′, and thereby assumes a fixed position state, Fingersare used to rotate a circular ring 18, whereupon a shaft member 12, apointed gear member 14, a small circular collar 15 and a large circularcollar 16 rotate in synchronization. The pin 121 reverse displaces anddepresses the ball bearing 35 downward, which thus recedes into alocating hole 37, thereby enabling the pin 121 to pass over the ballbearing 35 and position between the ball bearing 35 and an inserting pin38, at which time the ball bearing 35 flips upward, and a side portionof the ball bearing 35 presses on the pin 121.

Referring to FIGS. 4 and 5, which show the pointed protuberants 141respectively engaging an inner edge of a flange 621 of a base 62 of eachof the cartridges 60. Two flanges 241 of each protruberant 24 of thepacking member 20 latch onto a respective inner wall surface 361 of eachcartridge bore 36, and are thus not displaced along with displacing ofthe shaft member 12. The protuberants 24 abut against and thereby pressa rear wall surface of the flange 62, and with such a configuration thecartridges 60 are securely disposed within a casing 30.

Referring to FIG. 9, which shows that fingers 50 are able to quickly andeasily grasp hold of arc-shaped grooves 32 of the casing 30, and whichthereby enables the cartridges 60 to be respectively aligned withchambers of a cylinder 70. Referring to FIG. 10, after the cartridges 60have entered inside the cylinder 70, the circular ring 18 is thereuponreverse rotated, and, according to motion as depicted in FIGS. 6 and 7,the cartridges 60 are thereby released within the cylinder 70.

Primary characteristics of the present invention include design of thesuccessional arc-shaped grooves 32 configured on the circumferentialsurface of the casing 30, with which a user is able to utilize sense oftouch of the fingers 50 to quickly grasp hold of the casing 30 in anemergency or when in a dark environment. Hence, the present inventionrapidly achieves objectives, regardless of whether the objective isloading the cartridges 60 into the casing 30 or aligning the cartridgesfixedly positioned in the casing 30 and releasing the cartridges 60 intothe cylinder 70,
